A safety tie off device for use on roof or canopy structures includes a plate. The plate has a spacer bar and an anchor protruding substantially perpendicular to the plate. A locking assembly includes a knob or handle attached to a threaded rod, a locking plate, and a fastener connected to the locking plate. The device is configured to attach to a roof structure, thereby forming a detachable, stable safety tie off device for a user to anchor a safety harness.

A force damper arranged to progressively arrest a first force imparted by an object moving in a first direction is disclosed. The force damper includes a housing enclosure having a first housing end and a second housing end. The first housing end includes a first connection point, and the second housing end includes an opening. A driving member is disposed within the housing enclosure and includes a first shaft end, a second shaft end, and a shaft therebetween. The first shaft end includes a stop and the second shaft end includes a second connection point. A compressible member is disposed within the housing enclosure between the stop and the opening. The compressible member is formed from a material that at least partially undergoes plastic deformation when the first force is arrested and imparts a second force on the stop toward first housing end.

Various embodiments are directed to apparatuses and methods for detecting a workspace operating condition associated with a workspace. In various embodiments, an apparatus for detecting a workspace operating condition associated with a workspace may comprise an imaging device configured to capture imaging data, the imaging data comprising an image of a first connection location corresponding to a workspace anchor and a second connection location corresponding to an operator attachment; and a controller configured to detect a workspace operating condition associated with the workspace based on the imaging data; wherein the workspace operating condition is defined by a first connection status of a fall protection device at the first connection location and a second connection status of the fall protection device at the second connection location, wherein the controller configured to detect the first connection status and the second connection status based at least in part on the imaging data.

In at least one embodiment, a rooftop rigging support system mounts to a roof a building for suspending a load under an eave of the building. In some embodiments, the rooftop rigging support system comprises an arm that extends outward over the eave and then back inward underneath the eave. In some embodiments, the arm is a generally rigid, non-articulating structure. In some embodiments, the arm can be manually pivoted between a deployed position reaching under the eave and a withdrawn position extending above the roof.

A fall arrest assembly for anchoring a fall arresting line to a pair of roof trusses includes a truss mount that has a pair of channels each being integrated into the truss mount. The pair of channels is oriented parallel with respect to each other to insertably receive a beam of a respective one of a pair of roof trusses thereby mounting the truss mount to the pair of roof trusses. An anchor box is integrated into the truss mount and the anchor box has an anchor point which is integrated into the anchor box. In this way the anchor point can have a fall arresting line attached to the anchor point thereby facilitating the fall arresting line to be mounted to the pair of roof trusses.

A fall protection system includes an elevation mechanism including a base end and an elevated end, and that is configured to permit a user to scale the elevation mechanism. The first channel is disposed at a first side of the elevation mechanism and extends between the base end and the elevated end, and is configured to anchor a first shuttle to the elevation mechanism and permit the first shuttle to transition between the base end and the elevated end of the elevation mechanism. The second channel is disposed at a second side of the elevation mechanism and extends between the base end and the elevated end, and is configured to anchor a second shuttle to the elevation mechanism and permit the second shuttle to transition between the base end and the elevated end of the elevation mechanism.

Connectors for coupling fall arresting devices to a safety harness. The connectors may include a first pin configured to lock into a first side of a base portion using one or more locking mechanisms. The first pin may be used to engage with one or more fall arresting devices to attach the one or more fall arresting devices to the connector. In some such examples, the locking mechanisms may be positioned within interior portions of the first side of the connector so as to allow the one or more fall arresting devices to pivot freely about the ends of the connector. In some examples, the connectors may include a second pin configured to lock into a second side of the base portion using one or more locking mechanisms. The second pin may be used to conveniently and releasably attached the connector to a safety harness of a worker.

An expansion bolt and pivot and swivel mechanism therefor. The expansion bolt may have a base and a plurality of radially spreadable elongate elastic members cantileveredly projecting from the base at respective points of joinder to the base and terminating in respective spoons at respective points of joinder of the spoons, wherein the elongate elastic members have respective radially defined thicknesses at the points of joinder to the base that are substantially less than the corresponding thicknesses of the base, and respective radially defined thicknesses at the points of joinder of the spoons that are substantially less than the corresponding thicknesses of the spoons. The pivot and swivel mechanism may have a ring element that includes two spaced apart leg members having foot portions that turn to extend toward each other, the foot portions having respective, spaced-apart relatively enlarged ends; a swivel housing element having an open end for receiving and at least partially containing the ends of the foot portions so that the ring element can be substantially freely rotated about a pivot axis; and a capping element adapted for interlocking with the open end of the swivel housing element, the capping element having a bottom surface portion of radial symmetry about a swivel axis that is distinct from the pivot axis.

There is provided a system to install and remove an anchoring member on an anchorage structure in an overhead area. The system has a pole for providing access to the overhead area. The system further has a positioning arm for attachment to the pole. The positioning arm has a first end, and a second end offset from the first end. The positioning arm further has an elongated body having an outboard portion and an inboard portion, a recessed area formed in the outboard portion, and a dogleg shaped portion formed along the inboard portion. The system further has a safety hook assembly for attachment to the pole. The safety hook assembly has a hook end, and a safety latch mechanism having a safety latch engageable with the hook end. The safety latch mechanism is remotely operated by an operator, via a pull cord attached to the safety latch mechanism.
